Not sure what to think about PromptBox.
App looks nothing like what the sales page shows. It's plain vanilla and that's saying a lot.
Chrome extension.... Deprecated (Doesn't exist).
Missing many of the features that are shown.
With that being said, it looks like the App might be undergoing a complete overhaul. I'm willing to give the creator time to remedy the issues. I see it's potential as long as it resembles the product description.
